The construct of emotion dysregulation increasingly has been used to explain diverse psychopathologies across the lifespan. Difficulties in Emotion Regulation Scale (DERS; K. L. Gratz & Roemer, 2004) represents most comprehensive measure date and exhibits good reliability validity adults; however, yet be tested adolescents. present study examined psychometric properties DERS a community sample 428 adolescents (ages 13-17 years). Exploratory factor analysis supported 6-factor structure...
Abstract Event‐related potential studies of reward processing have consistently identified the feedback negativity (FN), an early neural response that differentiates indicating unfavorable versus favorable outcomes. Several important questions remain, however, about nature this response. In study, FN was recorded in to monetary gains and losses during a laboratory gambling task, temporospatial principal components analysis used separate from overlapping responses. The as positive deflection...
The present study examined electrocortical evidence for a negativity bias, focusing on the impact of specific picture content range event-related potentials (ERPs). To this end, ERPs were recorded while 67 participants viewed variety pictures from International Affective Picture System. Examination broad categories (i.e., pleasant, neutral, unpleasant) found no bias in two early components, N1 and Early Posterior Negativity (EPN), but revealed that unpleasant images did elicit larger late...
Abstract The error‐related negativity (ERN) currently appears as a physiological measure in relation to three Research Domain Criteria (RDoC) constructs: Cognitive Control, Sustained Threat, and Reward Learning. We propose conceptual model which variance the ERN reflects individual differences degree errors are evaluated threatening. also discuss evidence for placement of “Sustained Threat” construct, well that may more specifically reflect sensitivity endogenous threat. Following this, we...
Generalized anxiety disorder (GAD) and major depressive (MDD) are so frequently comorbid that some have suggested the 2 should be collapsed into a single overarching "distress" disorder.Yet there is also increasing evidence categories not redundant.Neurobehavioral markers differentiate GAD MDD would helpful in ongoing efforts to refine classification schemes based on neurobiological measures.The error-related negativity (ERN) may one such marker.The ERN an event-related potential component...
The current study investigated the association between neural engagement with task-irrelevant images and subsequent interference target processing using Emotional Interrupt paradigm [Mitchell, D., Richell, R., Leonard, A., & Blair, R. Emotion at expense of cognition: Psychopathic individuals outperform controls on an operant response task. Journal Abnormal Psychology, 115, 559, 2006]. Consistent previous studies, PCA-derived factors corresponding to early posterior negativity, P300, late...
Abstract The current study examined whether punishment has direct and lasting effects on error‐related brain activity, this effect is larger with increasing trait anxiety. Participants were told that errors a flanker task would be punished in some blocks but not others. Punishment was applied following 50% of during the first half experiment (i.e., acquisition), never second extinction). ERN enhanced both experimental phases—this enhancement remained stable throughout extinction phase. More...
The ability to detect and respond errors is critical successful adaptation a changing environment, variation in error-related brain activity has been linked psychopathology. negativity (ERN), an event-related potential component, represents unique neural response generated the anterior cingulate cortex (ACC). In present study, we measured ERN sample of individuals with Generalized Anxiety Disorder (GAD), Obsessive Compulsive (OCD), Major Depressive (MDD), or some combination 3. Also included...
Both exaggerated and attenuated responses to emotional stimuli have been documented in Generalized Anxiety Disorder (GAD). Event-related potentials are well-suited for examining the time-course of neural activity during processing; early components (e.g., P1) appear index relatively automatic attention stimuli, whereas later positivities late positive potential or LPP) dynamic allocation stimuli. Twenty-one individuals with GAD 25 healthy controls (HC) passively viewed neutral images while...
The error-related negativity (ERN) is a negative deflection in the event-related potential (ERP) following an erroneous response and thought to reflect activity of anterior cingulate cortex. There accumulating evidence that component has trait-like properties; prior further suggests test-retest reliability estimates ranging from .40 .82 over period 2 6 weeks. present study examined temporal stability longer time period. Error-related brain was recorded 26 subjects during arrow version...
Depressive disorders are associated with significant economic and public health burdens as well increased morbidity. Yet, perhaps due to the heterogeneous nature of disease, prevention intervention efforts only moderately efficacious. A better understanding core mechanisms depressive might aid in development more targeted intervention, help identify individuals at risk. One mechanism that may be particularly important phenotypes is reward insensitivity. Examination neurobiological correlates...
Abnormal patterns of attention to threat and reward have been proposed as potential mechanisms dysfunction in anxiety unipolar depressive disorders. However, few studies simultaneously examined whether these are shared among disorders or distinguish between them. In the present study, we recorded Late Positive Potential (LPP), an event-related putative index motivated attention, from 145 patients with 32 controls, they viewed blocks rewarding threatening images, respectively. We found that a...
Researchers in clinical psychophysiology make several methodological decisions during the analysis of event-related potentials (ERPs). In current study, we review these choices from perspective individual differences. We focus on baseline period and reference scheme (i.e., average, mastoid, source density), as well regarding where single electrode site vs. pooling sites), when area, area around peak), how subtraction- or regression-based difference scores) to quantify ERPs. To illustrate...
